JSON object and JSON string transfer (4 ways of conversion)

There are many ways to convert JSON characters to and from JSON objects:

1. How the jquery plugin supports conversion :

//

2. browser supported conversion Mode (FIREFOX,CHROME,OPERA,SAFARI,IE9,IE8) and other browsers:

// You can convert a JSON string into a JSON object //

Note: IE8 (compatibility mode), IE7 and IE6 do not have JSON objects, it is recommended to use the official JSON method, the introduction of Json.js.

3. how JavaScript supports conversion :

// You can convert a JSON string to a JSON object, noting that you need to wrap a pair of parentheses outside the JSON character

Note: IE8 (compatibility mode), IE7 and IE6 can also use eval () to convert strings to JSON objects, but these methods are not recommended, which is unsafe for eval to execute an expression in a JSON string.

4. The official JSON conversion method :

http://www.json.org/provides a json.js so that IE8 (compatibility mode), IE7 and IE6 can support JSON objects as well as their stringify () and Parse () methods;
Can get this JS on Https://github.com/douglascrockford/JSON-js, generally now use json2.js.
